Men who report watching a lot of pornography tend to have less volume and
activity in regions of the brain linked to rewards and motivation, says a
new German study.
The study, published in JAMA Psychiatry, can’t say watching porn caused the
decrease in brain matter and activity, however.
It’s not clear, for example, whether watching porn leads to brain changes
or whether people born with certain brain types watch more porn, said Simone
Kühn, the study’s lead author from the Max Planck Institute for Human
Development in Berlin, in an email.
“Unfortunately we cannot answer this question based on the results of the
present study,” Kühn said.
But, she noted, the results provide the first evidence for a link between
pornography consumption and reductions in brain size and brain activity in
response to sexual stimuli. | i***l
